Robustness of non-Gaussian entanglement against noisy amplifier and attenuator environments
Krishna Kumar Sabapathy, J. Solomon Ivan, R. Simon
The recently developed Kraus representation for bosonic Gaussian channels is employed to study analytically the robustness of non-Gaussian entanglement against evolution under nois…

Operator-sum Representation for Bosonic Gaussian Channels
J. Solomon Ivan, Krishnakumar Sabapathy, R. Simon
Operator-sum or Kraus representations for single-mode Bosonic Gaussian channels are developed, and several of their consequences explored. Kraus operators are employed to bring out…

A measure of non-Gaussianity for quantum states
J. Solomon Ivan, M. Sanjay Kumar, R. Simon
We propose a measure of non-Gaussianity for quantum states of a system of oscillator modes. Our measure is based on the quasi-probability . Since any meas…
